Tool Steel Machining Services
PRECI5 provides high-precision CNC milling, turning, wire EDM, and surface grinding for industrial tool steels. From cold-work dies to thermal-fatigue hot-work tooling, our advanced machining processes achieve tolerances down to ±0.005 mm across annealed, pre-hardened, and hardened conditions.
Tight Tolerances
Precision CNC machining achieving tight dimensional limits down to ±0.005 mm on critical mold and die tooling.
Hard Machining to 62 HRC
Specialized carbide and CBN tooling enables direct high-speed milling and turning on fully through-hardened steels.
Thermal & Stress Management
Integrated pre-stress relieving, vacuum heat treating, and cryogenic cycles ensure total dimensional stability.
Full CMM Inspection
Complete traceability with raw material certifications, hardness inspection, and automated 3D optical/CMM reports.
Engineered Machining for Industrial Die and Tool Alloys
Tool steels are alloyed specifically to provide distinct combinations of high hardness, wear resistance, toughness, and thermal strength. Machining these metals requires rigorous cutting parameter calculation, rigid toolholding, and advanced chip evacuation to prevent workpiece work-hardening and micro-cracking.
Whether your project requires high-carbon cold-work alloys like D2 and A2, versatile oil-hardening O1, hot-work die casting H13, or shock-resistant S7, PRECI5 provides end-to-end component engineering. Explore our detailed tooling alloy profiles below to inspect mechanical specifications, typical applications, and precision machining capabilities.
